[−][src]Enum cursive::utils::span::IndexedCow
A span of text that can be either owned, or indexed in another String.
Variants
Indexes content in a separate string.
Fields of Borrowed
Owned(String)
Owns its content.
Implementations
impl IndexedCow
[src]
pub fn resolve(&'a self, source: &'a str) -> &'a str
[src]
Resolve the span to a string slice.
pub fn as_borrowed(&self) -> Option<(usize, usize)>
[src]
Return the (start, end)
indexes if self
is IndexedCow::Borrowed
.
pub fn as_owned(&self) -> Option<&str>
[src]
Returns the embedded text content if self
is IndexedCow::Owned
.
pub fn from_cow(cow: Cow<'_, str>, source: &str) -> IndexedCow
[src]
Returns an indexed view of the given item.
Note: it is assumed cow
, if borrowed, is a substring of source
.
pub fn is_empty(&self) -> bool
[src]
Returns true
if this represents an empty span.
pub fn offset(&mut self, offset: usize)
[src]
If self
is borrowed, offset its indices by the given value.
Useful to update spans when concatenating sources. This span will now
point to text offset
further in the source.
pub fn rev_offset(&mut self, offset: usize)
[src]
If self
is borrowed, offset its indices back by the given value.
Useful to update spans when removing a prefix from the source.
This span will now point to text offset
closer to the start of the source.
This span may become empty as a result.
